Observation Location: Gavins Pond Dam
Common Name: Galerucella beetle larvae
Scientific Name: Galerucella calmariensis (or G. pusilla)
Comments: Galerucella beetles eat only purple loosestrife, an invasive exotic weed that has been displacing native wetland plants and reducing biodiversity. The Neponset River Watershed Association has been “ranching” and releasing Galerucella beetles, and they are now showing up in Sharon.
